Definitions

  • This invention relates in general to rolling mill construction and in particular to a new and useful rolling mill, particularly for cold shaping having rolls mounted in a driving sleeve arrangement for effecting better driving efiiciency and easy removal and replacement of the rolls.
  • the present invention has particular application with respect to rolling mills where several horizontal roll pairs are arranged in successive arrangement and where they would be likely to be arranged for cooperation with vertical rolls arranged in a shaping plane.
  • Devices which manufacture sections from strip material and which include several successively arranged stands with horizontal and vertical shaping rolls.
  • the shaping rolls may continue until the desired finish shaping is achieved by employing rolls having a cross section formed corresponding to the individual stages of deformation.
  • These working shafts are mounted in housings by chocks.
  • the shaping rolls themselves are usually arranged between the housing and in some instances they are partly arranged outside the housing in an overhung position.
  • Devices of this nature sometimes'include vertical rolls which are also partly mounted outside the housings and in transverses which also connect the two working shafts.
  • the disadvantage of such constructions is that it is difiicult to effect disassembly of the rolls which may be required for replacement of same.
  • a novel construction of roll stand which includes a novel mounting for the rolls permitting their easy removal and replacement, and further permitting a better and more expedient utilization of the rolling program in a shaping mill where several of the cold shaping rolling mills of different size and having different working shaft diameters are employed.
  • the working shafts which carry the horizontal rolls are secured against axial displacement and are engaged in a driving sleeve member which is rotatably mounted at the bearing of the housing.
  • the sleeve member advantageously includes means for easily connecting the sleeve for transmission of a driving torque and may easily be coupled to the shaft of the roll such as by squaring, splines, or even by wedging or keying.
  • the working side of the chock in the roll stand is advantageously, mounted so that it may be removed from the roll stand together with the working shaft which is assigned to it.
  • one of the upright supporting elements of the stand rotatably carries the removable chock or sleeve, and the other stand carries a chock having abutrnents which prevent axial displacement of the roll stand and transmit axial forces.
  • a driving torque may be introduced into the sleeve carrying the working shaft which is transmitted to the shaft for operation.
  • the new working shaft may have a diameter differing from the first shaft at the location where the shaping rolls are in contact.
  • the invention makes it possible where there are several systems for section production in a shaping mill to provide many shaping roll sets of a variety of diameters in order to expedite the programming.
  • a cold shaping rolling mill having overhung horizontal rolls and vertical rolls working in conjunction with the horizontal rolls in the same plane, it is advantageous for the easy and rapid removal of the rolls too lodge one of the two horizontally extending vertical roll holders in a separate auxiliary housing arranged laterally of the roll stand.
  • the other roll holder is guided between the working side chock of the upper and lower horizontal roll and is fastened to the roll stand.
  • the auxiliary housing can be braced againstthe roll stand by means of tractor screws arranged on both sides.
  • a further object of the invention is to provide a roll stand in which the working shaft of the rolls is secured in a rotatable sleeve member of one of the upright elements of the roll stand housing.
  • a further object of the invention is to provide a roll stand having an arrangement for mounting the rolls to permit their easy removal and replacement for facilitating rapid change of rolls.
  • a further object of the invention is to provide an improved roll stand including a roll stand housing having uprightstand elements each carrying chocks for rotatably supporting the rolls wherein one of the chocks includes a displaoeable sleeve member which is adapted to be directly connected to a torque applying device for driving the roll, the sleeve member being easily securable to the driving shaft of the roll stand for transmitting the torque thereto.
  • a further object of the invention is to provide a rolling mill and roll stand therefor which is simply in design, rugged in construction and economical to manufacture.
  • FIGS. 1a and lb are a partial side elevation and partial transverse sections of a complete roll stand with an auxiliary roll housing constructed in accordance with the invention taken on lines la, b; la, b of FIG. 3;
  • FIG. ,2 is a partial plan and partial sectional view taken on the line 22 of FIG. 1;
  • FIG. 3 is a partial end elevation and partial sectional view taken on the line 33 of FIG. 1.
  • a roll stand generally designated 60 which includes a roll stand base portion 3 on each side of which are carried upright stand elements 3a and 317 for the working side and drive side respectively.
  • a lower chock assembly generally designated 4
  • an upper chock assembly generally designated 5
  • a laterally spaced lower chock assembly generally designated 6
  • upper chock assembly generally designated 7
  • All of the chock assemblies 4, 5, 6 and 7 are adjustably carried in guide ways 8 and 9.
  • the working side chocks 4 and 5 are designed so that they permit an axial displacement in relation to the span.
  • the drive side chocks 6 and 7 carry an abutment which prevents the chocks from moving axially.
  • the working shafts 1a and 1b are mounted in the working side chocks 4 and 5 respectively by means of multi-roll roller bearings 11.
  • the arrangement of the roller bearings together with the chocks is such that there is produced between the center of the upper working shaft, 1b and the center of the lower working shaft 1a, a minimum dimension so that sections can still be rolled which for their production require shaping rolls of minimum diameter.
  • connection between the shaft 1a and the sleeve 13 is made by providing the working shaft with an external square 19 and the sleeve 13 with a corresponding internal square.
  • a selected geometrical cross sectional form such as a triangle, a polygon, or a so-called K-profile may be made to insure a positive transmission of the torque in a radial direction.
  • the connection may also be established through a r'nulti-wed'ge shaft and a multiwedge bushing or through spline and similar known means.
  • a transverse wedge 14 which extends through thesleeves 13, 13 and the associated working shaft.
  • the wedge 14 carries at its tapered end a thread 15.
  • the transverse wedge 14 is secured against displacement by a disc 16 and nut 17 which is secured over the thread 15.
  • a cylindrical or conical pin or similar known means for the connection of the two cylindrical parts may be used.
  • the sleeves 13 of each chock 6 and 7 carry on their outermost ends a flange 18 provided for coupling an element such as a cardan s haft 'or similar means for imparting a driving torque to "the sleeve.
  • Each sleeve 13 is mounted within its associated chock assembly on roller bearing 20.
  • the arrangement of such roller bearing and the chocks 6 and 7 are such that shaping rolls of minimum diameter can be used.
  • Axial forces are absorbed by thrust bearings 21 and 22 acting on both sides of the shaft and carried within the chock assemblies 6 and 7.
  • Bearings 21 and 22 transmit axial forces through the abutment 10 to the'roll stand.
  • the adjustment of the upper chocks and 7 vertically is made through threaded spindles 24 which are moved through a worm gear 25 by means of a hand Wheel 26.
  • the vertical adjustment of the lower chocks 4 and 6 is made through pressure screws Between the working side chocks 4 and 5 'of the upper and lower horizontal rolls 1a and 1b there is located a vertical roll holder 28 which permits adjustment for a spindle 29 of a vertical roll shoe 30 and hence of a vertical roll 31 which is carried by the shoe. On the opposite side the same arrangement of a vertical roll holder 28 spindle 29 and vertical roll shoe 30 with vertical roll 31 is provided.
  • the right and left vertical rolls which are to be employed may be of different forms when the section to be reproduced by rolling so requires.
  • the vertical roll holder 28 has an arm 32 on which is rotatable an axle 34 on which a sprocket wheel 33 is afiixed.
  • Shaft 34 extends outwardly so that it may be rotated by suitable means such as a wrench for adjustment of the left vertical roll 31 from one side.
  • the right hand vertical roll arrangement is connected with the stand, but the left hand vertical roll arrangement, which consists of the roll holder 28, spindle 29 and roll shaft 30 with rolls 31 is carried by separate auxiliary stand 35.
  • the auxiliary stand 35 is connected by means of two tractor screws 36 with the actual roll stand 33 (FIG. 2).
  • the sprocket wheel 33 connects to a sprocket wheel 62 through a sprocket chain 64. Rotation of the sprocket wheel 62 is effective to shift the position of the roll shaft 30 which rotatably supports one of the vertical rolls 31.
  • the auxiliary stand 35 and the roll stand 33 are fastened by means of bolts 37, 37 and 38, 38 respectively, to the base plate 39. To permit satisfactory alignment the stand 3 and the auxiliary stand 35 are guided by a spline connection.
